Optimal Signature Design for Spread-Spectrum Steganography
TL;DR: This work derives jointly optimal signature and linear processor designs for SS embedding in linearly modified transform domain host data and demonstrates orders of magnitude improvement over current SS steganographic practices.

Wavelet Based Image Watermarking: Futuristic Concepts in Information Security
TL;DR: The state-of-art of the various wavelet based image watermarking techniques in spatial as well as in transform domain based on the robustness, imperceptibility, capacity and security are reviewed.
Journal ArticleDOI
LDFT-Based Watermarking Resilient to Local Desynchronization Attacks
TL;DR: Simulation results show that the proposed watermarking scheme can survive numerous kinds of distortions, including common image-processing attacks, local and global DAs, and noninvertible cropping.

Optimized watermarking technique using self-adaptive differential evolution based on redundant discrete wavelet transform and singular value decomposition
TL;DR: Experimental results demonstrate that in addition to achieving a great imperceptibility, large capacity and sufficient security, the proposed scheme obtains a satisfactory level of robustness against image processing and geometrical attacks, simultaneously.

Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.

Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.

A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.
Journal ArticleDOI
Image coding based on a fractal theory of iterated contractive image transformations
TL;DR: The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations, that relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis and approximates an original image by a Fractal image.
